Routing locally generated traffic on fwmark

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'd like to route locally generated traffic via a particular interface
based on its mark value.

>From what I have researched, this is theoretically possible and lots of
people have tried it, but nobody has got it working.

Here's my rules:

# Mark the packets
iptables -A OUTPUT -t mangle -d 89.16.176.81 -j MARK --set-mark 0x800

# Route the marked packets via routing table T2:
ip rule add fwmark 0x800/0xffff table T2

# Force T2 packets out of the interface ppp1
ip route add table T2 default dev ppp1 via 94.30.127.76

# Flush the cache, just in case
ip route flush cache

However, the packets still go out of the default route (ppp0).

cwdwr:~# ip rule
0:	from all lookup local 
32765:	from all fwmark 0x800/0xffff lookup T2 
32766:	from all lookup main 
32767:	from all lookup default 

cwdwr:~# ip route show table T2
default via 94.30.127.76 dev ppp1 

Any ideas? Should this be possible?

Thanks,

Andy
